Try this thought experiment: You decide to donate money to Mitt Romney. You want change in the Oval Office, so you engage in your democratic right to send a check. Several days later, President Barack Obama, the most powerful man on the planet, singles you out by name.

His campaign brands you a Romney donor, shames you for "betting against America," and accuses you of having a "less-than-reputable" record. The message from the man who controls the Justice Department (which can indict you), the SEC (which can fine you), and the IRS (which can audit you), is clear: You made a mistake donating that money. -Kimberley A. Strassel

The Obama administration has an enemies list, and John Dodson was on it. The special agent for the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) infuriated his superiors by alerting Congress and everyone else about the government’s gunrunning scheme called Fast and Furious. He had to pay for his act of good citizenship. The Justice Department’s inspector general concluded Monday that a high-ranking political appointee destroyed Mr. Dodson’s credibility and ruined a career.

On April 20, President Obama’s campaign named VanderSloot to the first presidential “enemies list” since the Nixon era. Eight private citizens were singled out for their donations to Romney. They committed no crimes, sought no attention, and yet they became the subject of Obama’s scorn.

VanderSloot is now facing persecution from the federal government. Kimberly Strassel reveals in The Wall Street Journal that two federal agencies — the Internal Revenue Service and Labor Department — both launched investigations of VanderSloot after his name appeared on Obama’s enemies list.
